The OP400 is the first monolithic quad operational amplifier
that features OP77-type performance. Precision performance is
not sacrificed with the OP400 to obtain the space and cost savings
offered by quad amplifiers.
The OP400 features an extremely low input offset voltage of less
than 150 μV with a drift of less than 1.2 μV/°C, guaranteed over
the full military temperature range. Open-loop gain of the OP400
is more than 5 million into a 10 kΩ load, input bias current is
less than 3 nA, common-mode rejection (CMR) is more than
120 dB, and power supply rejection ratio (PSRR) is less than
1.8 μV/V. On-chip Zener zap trimming achieves the low input
offset voltage of the OP400 and eliminates the need for offset

nulling. The OP400 conforms to the industry-standard quad
pinout, which does not have null terminals.
The OP400 features low power consumption, drawing less than
725 μA per amplifier. The total current drawn by this quad
amplifier is less than that of a single OP07, yet the OP400 offers
significant improvements over this industry-standard op amp.
Voltage noise density of the OP400 is a low 11 nV/√Hz at 10 Hz,
half that of most competitive devices.
The OP400 is an ideal choice for applications requiring multiple
precision operational amplifiers and where low power
consumption is critical.

APPLICATIONS INFORMATION
Total supply current can be reduced by connecting the inputs of
an unused amplifier to V−. This turns the amplifier off, lowering
the total supply current.

A dual instrumentation amplifier that consumes less than 33 mW
of power per channel is shown in Figure 31. The linearity of the
instrumentation amplifier exceeds 16 bits in gains of 5 to 200 and
is better than 14 bits in gains from 200 to 1000. Common-mode
rejection ratio (CMRR) is above 115 dB (G = 1000). Offset voltage
drift is typically 0.4 μV/°C over the military temperature range,
which is comparable to the best monolithic instrumentation
amplifiers. The bandwidth of the low power instrumentation
amplifier is a function of gain and is shown in Table 6.
The output signal is specified with respect to the reference input,
which is normally connected to analog ground. The reference
input can offset the output from −10 V to +10 V if required.

The OP400 is inherently stable at all gains and is capable of
driving large capacitive loads without oscillating. Nonetheless,
good supply decoupling is highly recommended. Proper supply
decoupling reduces problems caused by supply line noise and
improves the capacitive load-driving capability of the OP400.

BIPOLAR CURRENT TRANSMITTER
DIFFERENTIAL OUTPUT INSTRUMENTATION
AMPLIFIER
In the circuit of Figure 32, which is an extension of the standard
three op amp instrumentation amplifier, the output current is
proportional to the differential input voltage. Maximum output
current is ±5 mA, with voltage compliance equal to ±10 V when
using ±15 V supplies. Output impedance of the current transmitter
exceeds 3 MΩ, and linearity is better than 16 bits with gain set
for a full-scale input of ±100 µV.

The output voltage swing of a single-ended instrumentation
amplifier is limited by the supplies, normally at ±15 V, to a
maximum of 24 V p-p. The differential output instrumentation
amplifier shown in Figure 33 can provide an output voltage
swing of 48 V p-p when operated with ±15 V supplies. The
extended output swing is due to the opposite polarity of the
outputs. Both outputs swing 24 V p-p, but with opposite polarity,
for a total output voltage swing of 48 V p-p. The reference input can
set a common-mode output voltage over the range ±10 V. The
PSRR of the amplifier is less than 1 µV/V with CMRR (G = 1000)
better than 115 dB. Offset voltage drift is typically 0.4 µV/°C over
the military temperature range.

under 25 µV/mA. Line regulation is better than 15 µV/V, and
output voltage drift is under 20 µV/°C. Output voltage noise
from 0.1 Hz to 10 Hz is typically 75 µV p-p from the 10 V output
and proportionately less from the 7.5 V, 5 V, and 2.5 V outputs.
Figure 34 shows a circuit that provides outputs of 10 V, 7.5 V,
5 V, and 2.5 V for use as a system voltage reference. Maximum
output current from each reference is 5 mA with load regulation
